Some disciplines are inherently complex and challenging to learn. This research attempts to design an instructional strategy for CBL systems to simplify learning certain complex domains. Firstly, problem transformation, a constructionist instructional technique, is used to promote active learning by encouraging students to construct more complex artefacts based on less complex ones. Scaffolding is used at the initial learning stages to alleviate the difficulty associated with complex transformation processes. The proposed instructional strategy brings various techniques together to enhance the learning experience. A functional prototype is implemented with Object-Z as the exemplar subject. Both objective and subjective evaluations using the prototype indicate that the proposed CBL system has a statistically significant impact on learning a complex domain. CBL systems include Learner models to provide adaptable support tailored to individual learners. Bayesian theory is used in general to manage uncertainty in Learner models. In this research, a fuzzy logic based locally intelligent Learner model is utilized. The fuzzy model is simple to design and implement, and easy to understand and explain, as well as efficient. Bayesian theory is used to complement the fuzzy model. Evaluation shows that the accuracy of the proposed Learner model is statistically significant. Further, opening Learner model reduces uncertainty, and the fuzzy rules are simple and resemble human reasoning processes. Therefore, it is argued that opening a fuzzy Learner model is both easy and effective. Scaffolding requires formative assessments. In this research, a confidence based multiple test marking scheme is proposed as traditional schemes are not suitable for measuring partial knowledge. Subjective evaluation confirms that the proposed schema is effective. Finally, a step-by-step methodology to transform simple UML class diagrams to Object-Z schemas is designed in order to implement problem transformation. This methodology could be extended to implement a semi-automated translation system for UML to Object Models.

A quantitative, descriptive research study was conducted at a nursing college to investigate the nature of nursing learners' exposure to computer assisted instruction and computer-based learning, the perceived benefits of this exposure, and the problems that they had encountered. Learners, who had been exposed to computer assisted instruction and computer-based learning, participated. A self-administered, structured questionnaire was administered to collect data. The research results revealed that the learners had limited exposure to educational computer packages, and computer-based learning activities. They encountered numerous problems. Although the learners derived many benefits from computer assisted instruction, this did not result in effective learning. They indicated that they preferred computer assisted instruction more than traditional teaching methods. This study contributed towards recommendations on improving learners' access to the necessary facilities, equipment and educational computer software. The researcher also recommended strategies to ensure that computer assisted instruction is based on sound educational principles. / Health Studies / M.A. (Health Studies)

Um dos mais sérios desafios enfrentados pelas comunidades científica e acadêmica tem sido quebrar os paradigmas tradicionais da educação formal, que é apoiada basicamente na transmissão de conhecimento centrada no professor e que coloca o aluno de forma passiva no processo de ensino e aprendizagem. Da mesma forma que as instituições de ensino enfrentam este desafio, as empresas têm sentido também grande dificuldade na capacitação de seus funcionários de forma a acompanhar, com a mesma velocidade, a mudança de métodos e tecnologia, impostos por um mercado competitivo e globalizado. Para manterem-se competitivos neste contexto da globalização, as empresas buscam como fator diferencial, além de outros, o desenvolvimento de novos produtos de maneira mais eficiente diante das necessidades ditadas pelo mercado. Porém, a dificuldade de proporcionar um treinamento eficaz de seus funcionários, principalmente quanto ao desenvolvimento de novos produtos, pode representar uma restrição à competitividade das empresas. Como uma tentativa de sanar este quadro, foi desenvolvido um cenário de integração que está baseado em um modelo de referência e na vivência dos participantes em uma estória de desenvolvimento de produtos de uma empresa modelo. Porém, pela quantidade de assuntos novos abordados no cenário de integração, suas aplicações anteriores registraram falhas de aprendizagem pelo desnivelamento de conhecimentos e por características particulares de aprendizagem de cada participante. Assim, este trabalho propõe uma nova estrutura para o cenário de integração, baseada em sistemas computacionais para a preparação e ensino dos conceitos abordados no desenvolvimento de produtos, bem como a continuidade do aprendizado após a realização de cursos do cenário de integração. Ainda dentro da proposta deste trabalho, está a implantação desta nova configuração para o cenário de integração para alunos de graduação e a avaliação dos resultados obtidos nesta experiência. / One of the greatest challenges for scientific and academic communities has been to break the traditional paradigms of formal education, which are essentially based on the transmission of teacher-centered knowledge and which place the student in a passive role in the teaching and learning process. Just as educational institutions face this challenge, so do companies encounter serious difficulties in terms of capacitating their employees to cape with the methodological and technological changes brought about by a competitive and globalized market at the same rate that these changes occur. To remain competitive and meet the market- dedicated needs in this globalized context, companies seek more effective new product development methods, among others, as a differentiating factor. However, the difficulties involved in providing effective employee training, particularly insofar as new product development is concerned, may represent a restriction to the competitiveness of companies. In an attempt to reverse this situation, an integration scenario was developed based on a reference model and on the participants\' personal experience in the product development story of a model company. However, owing to the number of new subjects broached in the integration scenario, its previous applications revealed learning failures resulting from participants\' unequal degree of knowledge and their distinct learning characteristics. This work, therefore, proposes a new structure for the integration scenario based on computer systems for the preparation and teaching of the concepts applied to product development, as well as for continued learning following the integration scenario courses. The scope of this work also includes the implementation of this new configuration for the integration scenario for undergraduate students and the assessment of the results of this experience.

Abstract This study focuses on the process of self-regulated learning by investigating in detail how learners engage in self-regulated and strategic learning when studying in g/nStudy learning environments. The study uses trace methods to enable recognition of temporal patterns in learners’ activity that can signal strategic and self-regulated learning. The study comprises three data sets. In each data set, g/nStudy technology was used to support and trace self-regulated learning. In the analysis, micro-analytical protocols along with qualitative approach were favoured to better understand the process of self-regulated and strategic learning in authentic classroom settings. The results suggested that the specific technological tools used to support strategic and self-regulated learning can also be used methodologically to investigate patterns emerging from students’ cognitive regulation activity. The advantage of designing specific tools to trace and support self-regulated learning also helps to interpret the way in which the learning patterns actually inform SRL theoretically and empirically. Depending on how the tools are used, they can signal the typical patterns existing in the learning processes of students or student groups. The learning patterns found in the students’ cognitive regulation activity varied in terms of how often the patterns emerged in their learning, how the patterns were composed and when the patterns were used. Moreover, there were intra-individual differences – firstly, in how students with different learning outcomes allocated their study tactic use, and secondly, how self-regulated learning was used in challenging learning situations perceived by students. These findings indicate log file traces can reveal differences in self-regulated learning between individuals and between groups of learners with similar characteristics based on the learning patterns they used. However, learning patterns obtained from log file traces can sometimes be complex rather than simple. Therefore, log file traces need to be combined with other situation-specific measurements to better understand how they might elucidate self-regulated learning in the learning context. / Tiivistelmä Tässä väitöskirjassa tutkitaan oppilaiden itsesäätöisen ja strategisen oppimisen ilmenemistä oppimisprosessin aikana. Tutkimuksessa hyödynnetään g/nStudy- oppimisympäristöä, jonka avulla on mahdollista tukea ja jäljittää oppimisen strategista toimintaa. g/nStudy-oppimisympäristö tallentaa lokidataa, joka on tarkkaa ajallista informaatiota siitä toiminnasta, jota oppilas tekee työskentelynsä aikana. Toisin sanoen, lokidatasta on mahdollista jäljittää ne tiedot, jotka reflektoivat strategista – ja itsesäätöistä oppimista. Erityisenä mielenkiinnon kohteena oli selvittää miten lokidatasta voi löytää strategisia oppimisen toimintamalleja, ja miten nämä strategiset oppimisen toimintamallit vaihtelevat oppilaiden, oppilasryhmien ja erilaisten oppimisen tilanteiden aikana. Väitöstutkimus muodostuu kolmesta erillisestä tutkimusaineistosta. Jokaisessa kolmessa aineistossa on hyödynnetty g/nStudy-teknologian mahdollisuuksia tukea ja jäljittää itsesäätöistä oppimista. Tutkimusaineiston analyysissä hyödynnetään mikroanalyyttista lähestymistapaa sekä laadullista tutkimusotetta. Tutkimuksen analyyttinen lähestymistapa antaa mahdollisuuden ymmärtää itsesäätöisen- ja strategisen oppimisen ilmenemistä aidossa oppimistilanteessa. Tutkimustulokset osoittavat, että oppimisympäristöön sisällytettyjä teknologisia työkaluja voidaan käyttää tukemaan itsesäätöistä ja strategista toimintaa. Sen lisäksi samoja työkaluja voidaan käyttää myös menetelmällisenä välineenä tutkittaessa itsesäätöistä – ja strategista toimintaa erilaisissa oppimistilanteissa. Tutkimus -tulokset osoittavat, että oppimisen strategiset toimintamallit vaihtelivat oppilaiden – ja oppimistilanteiden välillä. Oppimisen strategisissa toimintamalleissa oli myös laadullisia eroja sen suhteen, miten usein ne ilmenivät oppimisprosessin aikana ja mistä strategisista toiminnoista ne koostuivat. Johtopäätöksenä voi todeta, että lokidatan käyttäminen tutkimusmenetelmänä edesauttaa paljastamaan opiskelun strategisia toimintamalleja oppilaiden – ja oppilasryhmien välillä. Tutkimuksen perusteella voidaan todeta, että strategiset toimintamallit voivat olla hyvinkin monimuotoisia. On tärkeää tunnistaa, missä tilanteissa ja milloin näitä toimintamalleja käytetään ja erityisesti mikä on niiden vaikutus oppimisen laatuun.

The purpose of this exploratory case study was to examine how student-to-teacher interactions encourage students to develop self-regulated learning (SRL) habits and skills. Zimmerman's social cognitive theory of SRL, which supposes a relationship between academic success and SRL, is used as a conceptual framework. The representative case is a computer-based alternative education program for students at risk of dropping out of high school in grades 10-12. The teachers worked one-on-one with students in a computer lab while the students engaged in mastery-based learning using Apex Learning Inc. digital curriculum. Five teachers responded to three questionnaires to examine how student-to-teacher interactions influenced student-to-content interactions, and students' forethought, performance, and evaluation behavior. The teachers also submitted instructional artifacts and described instructional tools, activity types, and scaffolds within the digital curriculum. After analysis of primary and secondary data, the results showed the following: Student-to-teacher interactions encouraged students to engage in forethought behaviors associated with goal setting and strategic planning; examples of performance behaviors were using the content to increase understanding, navigating the content efficiently and effectively, monitoring the use of task strategies, and developing thinking steps; and examples of evaluative behaviors were calibrating and making accurate self-judgments. The study can promote social change by helping students at-risk of dropping out of school develop SRL strategies correlated to academic achievement and high school graduation. SRL habits are transferable to everyday behaviors associated with continued employment, maintaining healthy relationships, and lifelong learning.

This study examined how learners construct textbase and situation model knowledge in hypertext computer-based learning environments (CBLEs) and documented the influence of specific self-regulated learning (SRL) tactics, prior knowledge, and characteristics of the learner on posttest knowledge scores from exposure to a hypertext. A sample of 160 undergraduate education majors completed measures of prior knowledge, goal orientation, intrinsic motivation, self-efficacy to self-regulate learning, and a demographic survey. They were trained in the use of nStudy, a learning environment designed to facilitate self-regulated learning from web-based media including hypertext and to trace learners' actions while they learned online. Learners completed a 20-minute study session learning about Attention Deficit Hyperactivity Disorder and a posttest to assess changes in knowledge scores. Results indicate that employment of individual SRL tactics including tendency to highlight was found to be associated with increased posttest knowledge scores across learners. Goal orientation and prior knowledge also significantly predicted posttest knowledge scores in regression models. These findings can be used to inform the design and use of hypertext in order to individualize computer-based instruction and maximize knowledge acquisition for students, based upon their individual characteristics. / Educational Psychology

Rationale: Audiology student training in New Zealand faces many difficulties with a limited number of qualified instructors and suitable external placements. With a continued shortage of audiologists in New Zealand, new methods of training need to be introduced and implemented. One solution is through the use of realistic, computer-based virtual patient simulators (VPS). HIT Lab New Zealand in conjunction with the University of Canterbury has designed a VPS for New Zealand audiology students. A speech audiometry component is to be developed based on best practice recommendations, and needs to be validated. Method: Two studies, one with 18 Master of Audiology (“expert”) and another with 18 (“novice”) undergraduate students, were evenly divided into simulator and non-simulator user groups. Simulator users had to complete 5 virtual patient cases in addition to the non-simulator users’ requirement to refer to provided lecture notes and speech audiometry protocols. Novice students were assessed on declarative, procedural and retained knowledge of speech audiometry; expert students were additionally assessed on training transfer. The intervention period was set at two weeks, and the retention assessment at four weeks post-intervention.   Results: Expert students who used the simulator significantly improved their training transfer skills. No significant differences were found between and within groups for declarative knowledge and procedural knowledge. Training transfer and procedural knowledge were retained for both groups, but only non-simulator users retained declarative knowledge. Novice students who used the simulator significantly increased their declarative knowledge. Both groups’ procedural knowledge significantly regressed post-intervention. Declarative and procedural knowledge were retained for both groups. Implications: Simulator use appears to accelerate learning outcomes otherwise achievable through traditional learning methods, and does depend on the users’ existing knowledge base. Regular use may be necessary to retain desired learning outcomes. Improvements (e.g., more detailed feedback systems) are to be incorporated into the simulator, and sole reliance on the simulator for learning is not recommended. Future research into more holistic aspects of virtual patient use within the field of audiology and allied health care is warranted.

Instructional Design (ID) ontology can be used to formally represent knowledge about the teaching and learning process, which contributes to automatic construction of personalised eLearning experiences. While ID ontologies have been continuously improved and developed over recent years, there are concerns regarding what makes a quality ID ontology. This study proposes a framework for evaluating the quality of an ID ontology by synthesising the crucial elements considered in the ID ontologies developed to date. The framework would allow a more precise evaluation of different ID ontologies, by demonstrating the quality of each ontology with respect to the set of crucial elements that arise from the ontology. This study also gives an overview of the literature on ID ontology, as well as the implications for future research in this area.

Hands-on experiential learning activities are an important component of computing education disciplines. Laboratory environments provide learner access to real world equipment for completing experiments. Local campus facilities are commonly used to host laboratory classes. While campus facilities afford hands-on experience with real equipment high maintenance costs, restricted access, and limited flexibility diminish laboratory effectiveness. Web-based simulation and remote laboratory formats have emerged as low cost options, which allow open access and learner control. Simulation lacks fidelity and remote laboratories are considered too complex for novice learners. A web-based combined laboratory format incorporates the benefits of each format while mitigating the shortcomings. Relatively few studies have examined the cognitive benefits of web-based laboratory formats in meeting computing education students’ goals. A web-based combined laboratory model that incorporates motivation strategies was developed to address non-traditional computing education students’ preferences for control of pace and access to learning. Internal validation of the laboratory model was conducted using pilot studies and Delphi expert review techniques. A panel of instructors from diverse computing education backgrounds reviewed the laboratory model. Panel recommendations guided enhancement of the model design.
